Scientists Develop Magnetic Field Analysis Technique to Authenticate Ancient Pottery

#magnetic field#pottery authentication#archaeology#artifact forgery

Researchers developed a method to authenticate ancient pottery by analyzing thermal remanent magnetization (TRM) and viscous remanent magnetization (VRM) differences, using temperature thresholds to distinguish genuine artifacts from forgeries. The technique leverages historical shifts in Earth's magnetic field to verify the age of clay objects, aiding in combating illicit antiquities trade.
